a couple of years ago I made a circuit with 9 squarewave-oscillators (using 3x CD40106) which fade in and out.
It also has a bunch of LED's which are mounted in a such a way that they create changing patterns, similar to my
LED mandala. I still have to make a suitable housing for it and I recently got my hands on two toy-TV music boxes,
so I was curious if that might fit. well, it didn't, but I did record a 10 minute demo drone. (with delay and reverb added)
